ABSTRACT:
Methods, apparatus and systems for multilevel data communication comprises dividing a set of information bits to be transmitted into a first group and a second group; encoding the first group to generate a block code, selecting a subset of symbols in a constellation of symbols in dependence on the block code according to a Gray-coded mapping function, selecting a symbol within the subset in dependence on the second group according to a Gray-coded mapping function, and transmitting the selected symbol.
